Jim Jefferies

Jim Jefferies is probably the least-known comedian on the list, but don’t worry -- he’s also the most likely to give your grandmother a heart attack with a single punch line.

The Australian native has spent the last decade conquering the comedy world, first in his home country, then in Britain, and now in North America where he’s already recorded specials for Comedy Central and HBO in just a short few years. He’s uncomfortably candid and viciously satirical, tearing down major institutions and telling stories about getting a wheelchair-bound friend a prostitute and having a vibrating egg stuck up his ass for several days.

He can do highbrow and lowbrow material equally well and does his best to offend every audience member at least once in any given show. Simply put, the guy is an incredible talent who will only get bigger and upset even larger groups of minorities as the years go on. If you can stomach it, this is the guy to watch. He’s already had a podcast removed from iTunes for being too offensive, and given that they have no content restrictions, that’s not an easy task.
